A hollow cylinder of length of \( 1 \mathrm{~m} \), inner radius (Ri) \( 0.03 \mathrm{~m} \) and outer radius (Ro) \( 0.06 \mathrm{~m} \) has a thermal conductivity \( (\mathrm{k}) 24.44 \mathrm{~W} / \mathrm{mK} \). The inside surface temperature is at \( 752.4 \mathrm{~K} \). What is the outside surface temperature of the cylinder when the rate of radial heat transfer is \( 4.44 \mathrm{~kW} \) ? Note - Include units in the answer Answer:
